And orcas even goal giant shark species, together with bullnose and tip sharks. Along with orcas, killer whales additionally goal sharks.
Sharks are focused as a result of their livers and intestines are wealthy in vitamins, stated researcher Jesús Erick Higuera-Rivas.
Researchers have even documented a number of such hunts. For instance, in a single case, they had been watching a shark on the floor of the water when an orca got here towards it, swimming previous it. However solely to return proper once more attempting to hit the shark’s tail. In line with the researchers, it is a looking approach.
One other case was recorded when an orca chased a thresher shark and ended up headbutting it, then attempting to seize it with its tail, based on Stay Science.
To this point, scientists say they do not know what affect such hunts might need on the ecosystem or whether or not the sharks will finally resolve to go away the world.
Rob Lott, a consultant of the charity Whale and Dolphin Conservation, who was not concerned within the examine, agrees. The results for the ecosystem are usually not but clear, he stated, however it’s clear that prime predators comparable to sharks play an necessary position in sustaining the steadiness of the ecosystem, and if their inhabitants strikes to different new locations, there might be penalties.
In spite of everything, orcas have been looking sharks for over 50 years, however we not often noticed them. And the brand new examine would not present that such hunts are taking place extra typically. It might merely be due to higher expertise at present, comparable to drones or underwater cameras, that such moments might be noticed and captured extra typically.
Nevertheless, in South Africa, two shark-eating orcas scared off a whole lot of nice white sharks and so they retreated from the Western Cape. Nevertheless, specialists can’t affirm whether or not this might additionally occur within the Gulf of California.
